Nanotechnology used for HVACR unit without refrigerant gases

A company has successfully operated a HVACR beta unit employing nanotechnology materials using no refrigerant gases.

The system, developed by Dais Analytic, and dubbed NanoAir, is projected to reduce energy usage and harmful emissions by over 50 per cent from today’s most efficient heating/cooling, and refrigeration equipment.

NanoAir is fully capable of heating, cooling, dehumidifying, or humidifying air using water and Dais’s nano-materials rather than ozone-depleting fluorocarbon (CFCs and HCFCs) refrigerants commonly used in today’s cooling/refrigeration equipment.

Scott Ehrenberg, chief technology officer, said: “NanoAir is the next breakthrough use of Dais’ nanotechnology materials. NanoAir has been shown by third party testing to have the ability to reduce energy costs and harmful emissions by over 50 per cent versus equipment in use today.”

Daikin has joined forces with the City of Bath College to showcase the latest generation, high efficient heating system, which will be used by students studying refrigeration and air conditioning courses.
